l W. ROBINSON. PLPGTROMAGNPTIG GATP OPERATING APPARATUS.

No. 105,494.l Patented July .19, 1870.

l side otf the gate, and which Yis shifted back to its normal position is determined by the ditravel of the train, being shifted out of rection lin working position by the train as it passes it, after hav- .ing traversed the crossing-,it only being necessarythat either apparatus shoul d be set going as the train approaches the crossing.

This may be effected by pivoting, as at k, the frame Gr that carries the circuit closer, and combining with the same, levers, on u, ar-y ranged so that the wheels of the vehicle or cars in the train will, by the direction ot' travel, first come in contactwith the y the action of the] its lever I, which pntA out of' reach but,

ever n, swing the frame G','so that operates the circuit-closer, will Vhe 'or Contact withthe passing train, after the train has passed the apparatus, the same bythe action of a weight or spring, r, on the tiame G, and whereby the lever I is returned to its original position for operation .of the circuit-closer hy a train coming in the reverse direction, and in which the lever or acted upon before the lever m. v

Connected with the apparatus .may hesupplexnentary electro-magnets, s s, that, when the circuit-closer H has closed the circuit, may, through the internention of' a suitable 4independent circnitcloser, be made lever mand depress-it, anch-thronglr I is struck to strike in repeated succession a bell, M, to sound an alarm as to the approach or passage of a train.

lVhat is here claimed, 'Letters Patent, is-f- 1. The'combinaton of the levers e c with the gate B and circuit-closer to abattery, arranged soas to-operate thc gate -hy theaction of the passing vehicle, substantially as spccitied. 2; The combination with a circnit-closer, arranged for operation by the vehicle, while in motion, of clockwork for .prolonging the action to said circuit-closer and operating to keep the armature of the' magnets in prolonged holden or control: of the gate, substantially as specified. 3. The `circuit-closer, or its' stand or frame, or a portion thereof', hung or arranged `so as to be shifted outrofwvorking position on and by a vehicle or' train Apassing in the one direction, and afterward returning to its normal position for control ot' thc circuit-closer 'by avchiclcor train passing in the oppositcdirection, essentially as herein set forth.
